mod_alias

URL aliasing.

default_index(ConfigDB, Path) -> NewPath

ConfigDB = config_db()

Path = NewPath = string()

If Path is a directory, default_index/2, it starts
searching for resources or files that are specified in the config
directive DirectoryIndex.
If an appropriate resource or file is found, it is appended to
the end of Path and then returned. Path is
returned unaltered, if no appropriate
file is found, or if Path is not a directory.
config_db() is the server config file in ETS table format
as described in
Inets Users Guide..

path(PathData, ConfigDB, RequestURI) -> Path

PathData = interaction_data()

ConfigDB = config_db()

RequestURI = Path = string()

path/3 returns the actual file Path in the
RequestURI (See RFC 1945). If the interaction data
{real_name,{Path,AfterPath}} has been exported by
mod_alias;
Path is returned. If no interaction data has been
exported, ServerRoot is used to
generate a file Path. config_db() and
interaction_data() are as defined in
Inets Users Guide.

real_name(ConfigDB, RequestURI, Aliases) -> Ret

ConfigDB = config_db()

RequestURI = string()

Aliases = [{FakeName,RealName}]

Ret = {ShortPath,Path,AfterPath}

ShortPath = Path = AfterPath = string()

real_name/3 traverses Aliases, typically
extracted from ConfigDB, and matches each
FakeName with RequestURI. If a match is found
FakeName is replaced with RealName in the
match. The resulting path is split into two parts, that
is ShortPath and AfterPath as defined in
httpd_util:split_path/1.
Path is generated from ShortPath, that is
the result from
default_index/2 with
ShortPath as an argument.

real_script_name(ConfigDB, RequestURI, ScriptAliases) -> Ret

ConfigDB = config_db()

RequestURI = string()

ScriptAliases = [{FakeName,RealName}]

Ret = {ShortPath,AfterPath} | not_a_script

ShortPath = AfterPath = string()

real_script_name/3 traverses ScriptAliases,
typically extracted from ConfigDB, and matches each
FakeName with RequestURI. If a match is found
FakeName is replaced with RealName in the
match. If the resulting match is not an executable script
not_a_script is returned. If it is a script the
resulting script path is in two parts, that is
ShortPath and AfterPath as defined in httpd_util:split_script_path/1.
